1 Claim. (Cl. 229-14) 7. This invention relates to a package.

The object of the invention is to provide a novel and improved lined package in which provision is made for closing and sealing the'mouth of the In accordance with th present invention, the carton is provided with but two opposed top closing flaps, the narrower opposed flaps being eliminated, whereby to enable such top closures to be liner in a novel and improved manner. more readily and conveniently performed upon With this general object in view and such existing machines in which the mechanism for others as may hereinafter appear, the invention bending the end ,fiaps outwardly maybe elimiconsists in the package hereinafterdescribed and nated. In addition, the elimination of the two particularly defined in the claim at the end of opposed narrow end closing flaps serves to reduce this specification. 7 lo the bulk or thickness of the complete top closure In the drawing illustrating the preferred emthus enabling a heater appearing package to be bodiment of the invention, Fig. 1 is a perspective produced. view of a lined package embodying the present In order to efiectively seal the carton at the invention; Fig. 2 is a similar view showing the ends where the closing flaps are omitted, the folded lining top closure laid against the top'of present carton is provided with sealing wings the package; Fig. 3 is a perspective view illustratupon one of the remaining side flaps which are ing a preferred form of seal for the mouth of-the' arranged to close over the adjacent edges oi the lining; and Fig. 4 is a cross-sectional view showcarton to form a relatively tight and efficient seal ing the construction oi'the package after it has for the top of the carton. been closed and sealed. Referring now to the drawing, l0 represents a In general, the present invention findiiparpackage or carton provided with but two opposed ticular use in the production of a lined package closing flaps I2, H, the latter being provided with comprising a lined carton having a novel and end sealing wings l6, l8. The package is proimproved top closure which is characterized by vided with a suitable inner liner or bag 20 within the provision of but two opposed closing flaps for the carton, and the mouth of the lining is arthe top of the carton and in which the mouth of r n ed o p oject above the top of the opened the lining is provided with a closure such as to package, as illustrated in dotted lines in F g. 1. reduce to a minimum the liability of leakage of The illustrated top cl u for the mouth o t e the material therethrough.

Thus, bending the flaps outwardly and for retaining an efiicient and effective top closure for the lining them in this position duringthe folding operation and the carton is provided without the use of the had to be provided. usual narrow end flaps of the carton.

A In order to provide a sealed closure for the mouth portion 32 of the lining in a simple and eflicient mannenthe mouth portion extendin beyond the edge of the closed flap' Il may be closed by a sealing stripv 34 which may besecured overthe extended mouthportion 32 and mengagement withthe inner surface of the closing flap II, as clearly shown in Fig.3. Thereafter,

the carton closing flap ll provided with the sealing wings l6, "I8, is folded over the top of the ton having but two top closing flaps formed asextensions, of two opposed walls of the carton, a

lining bag within the carton having a top closure lining and the fiap ll together with the sealing strip 34 is provided with a coating of adhesive.

The completely closed and sealed carton, as illusj trated in Fig. 4 shows thesealingstrip llfancl flap l2 adhesively secured to the top of the flap I4, and the mouth portion 32 interlocked between the upperand lower carton'ilapsina manner formed by folding inwardly two opposed portions of the top thereof and bringing the remaining opposed portions together to form an elongated tab having a pleat in each end, said tap being r folded to lie ilat on top of the lining bag and such as to provide a secure and: positive' seal 'of the lining bag and the outer carton.

From the above description, it will be seen that the construction of the-presentpackage is such as to facilitate the performance of the top closing operation for the mouth of thelli'ning and enables an eflicient carton closure to be made in a manner such asto 'eilectively seal thecontents of the; container in a novel and improved I manner-with but two of the closingilaps.
